Short-circuit interrupting capacity hits 187 kA at 240 V and still holds 121 kA at 415 V and 440 V, which covers most industrial service-entrance and distribution applications without needing a current-limiting upstream device. The IP40 front protection keeps dust and tools out of the mechanism in a clean indoor panel; no washdown rating, so keep it inside the enclosure. Footprint is 184 mm wide by 248 mm tall by 110 mm deep. The 184 mm width occupies four pole spaces on the DIN rail or bolted busbar assembly. Maximum power loss is 37.5 W — that's the heat the breaker dumps into the enclosure at full rated current. In a sealed panel with multiple breakers ganged, factor this into the thermal budget to avoid nuisance tripping from ambient rise. ## Trip unit and protection capabilities The ETU550 is an electronic trip unit with communication function — it supports Modbus RTU or PROFIBUS via the 3VA2 communication module, so you can pull trip data, load profiles, and event logs into the plant SCADA or BMS without adding a separate power meter. No undervoltage release or shunt trip is built in; those are add-on accessories that mount on the left side of the breaker. The adjustable trip curves let you coordinate with downstream feeders, but the minimum continuous current setting is 375 A and the maximum is 3 000 A, so this frame is sized for a main or large feeder role.","metaTitle":"Siemens 3VA2325-5JP42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU5","metaDescription":"Siemens 3VA2325-5JP42-0AA0 SENTRON molded case circuit breaker, 250 A continuous, 4-pole, ETU550 electronic trip unit.
